Analysing 148 465 US veterans, researchers from the VA Boston Healthcare System, uncovered the effects of chocolate in a long-term diet. The average age was 64 per cent and 90 per cent were men. None of the participants had previously experienced heart disease.

Over the course of two and half years, scientists tracked how often the test subjects consumed 28 grams of chocolate. Over the length of the study, 2.7 per cent experienced some sort of coronary artery disease (CAD).

Surprisingly, veterans who included 5 or more servings of chocolate each week were less likely to be included in the 4 065 that experienced heart-related illnesses. Overweight vets with no chocolate in their diet were most at risk.
